FASTJEBOABD TRAY. I

Application filed July 21, 1916, Serial No. 110,507.

To all whom it may concern:

Be it known that I, HARRY G. HALL, a citizen of the United States,residing at Atlanta, in the county of Fulton and State of Georgia, haveinvented new and useful Improvements in Pasteboard Trays, of which thefollowing is a specification.

This invention has relation, generally, to receptacles of cardboard, orother suitable material, but it more specifically comprehends a trayconstruction efi'ected from a blank cut and scored in a predeterminedmanner.

The fundamental object of this invention resides in providing acontainer, tray-like in contour and formed from a blank so scored andcut when its several sections have been normally positioned, theordinarily con-- sidered weak factors in box construction will bereinforced and thoroughly protected, so as to remain intact under themost adverse circumstances.

Another and further object of this inven tion is to design a novel formof tray, capable of functioning as a container for such substances asbutter, lard or articles of food associated with a preserving liquidwhich would be detrimental to the life of the commonly constructedcardboard receptacle.

Another and still further object of this invention is to provide a trayformed from a blank embracing a multiplicity of sections which may beexpeditiously and conveniently brought to and locked in proper position,with aminimum expenditure of time and labor.

Further objects of this invention are to provide a tray-like containerhaving the upper edges of its side sections formed with a combinationlocking and reinforcing flap, to materially increase the strength of thebox, and effect a more secure holding together of the parts; andfinally, a receptacle having certain herein-after mentioned structuralcharacteristics and features, by virtue of which improved and beneficialresults are accomplished.

Briefly stated, this invention comprises a cardboard blank cut andcreased to produce a plurality of sections, namely, bottom, end and sidesections, the latter being provided at their upper edges with outwardlyand downwardly foldable locking and reinforcing flaps, adapted tooverlie and engage certam lockin members carried by the end sections,which latter are situated with their Specification of Letters Patent.

upper edges coincident with those of the side sections when the box isproperly folded, whereupon said sections may be securely maintained inproper folded relation.

Fig. 6 is a perspective view of the completed tray.

In the manufacture of a cardboard receptacle from a blank, it isabsolutely essential, in order to satisfy the rigid servicerequirements, that interlocking of the assembled sections be such as toeliminate any possibility of a sudden and unexpected collapse,consequently, to meet this requisite, it is necessary to effectivelyreinforce all exposed parts, such as corners, edges, etc, and also unitethe sections ofthe blank in a manner to make accidental disengagement ofthe interlocked parts impossible, and it is to this end that l havedesigned the tray constituting the subject matter of this invention.

lln the illustrated embodiment characterizing this invention, there isshown a traylike receptacle formed from ablank developed in accordancewith Fig. 1. The central portion 1 of the blank, within the confines ofscores 1", constitutes the bottom of the tray. Adjoining bottom section1, but separated from it by scores 1, are the end sections 2, the widthof which should correspond to the desired depth of the container. Eachend section 2 is provided with an angularly shaped ofi-setting wing 3,the outlines of which are defined by scores 2 and 8 Also adjacent bottomsection 1, and.

divided therefrom by scores 1*, are side sections 4, whose widthscorrespond to that of end sections 2. These sections 4: are formed ontheir upper edges with locking flaps 5, the purpose of which will behereinafter described.

Within the angle set forth by'tlie lateral edges of side sections 4 andscores 3? of wings 3, are the reinforcing sectionally formed corners 6,the respective sections thereof being designated 7 and 8, and dividedfrom one another by scores 7. Carried by the corners 6 and extendinglaterally therefrom with their extremities coincident with the upperedge of flap 5, when the blank is in a developed state as shown in Fig.1, are the locking members 9, the combined length of which, whenoperatively disposed, is equal to the width of end sections 4:. As thelocking members 9, to be effective, must necessarily, to a certainextent, be separate from the corner sections, the latter are cut on theline 8, as clearly shown in Fig. 1. After the blank is out and creasedas above described, to dispose the several sections in suitablerelation, the sidesections are folded on scores 1, until in a planesubstantially at right angles to bottom section 1. In the meantime, asside sections 4 are brought to the aforesaid position, the sections 8 ofthe reinforcing corners 6 will assume the position shown in Fig. 2, inother words, said sections 8 will be angularly disposed with respect tosections 7; having positioned the side sections, end sections 2 are nextfolded inwardly on scores 1 to an extent sufficient to bring scores 8 ofthe corner sections contiguous scores 4 of the side sections. Duringthis operation, the inner surfaces of sections will'be disposed insuperposed relation with respect to the inner surfaces of sections 8,preparatory to folding into reinforcing position. Then saidreinforcingcorners, embracing sections 7 and 8, are folded on scores 3inorder to bring the outer surface of sections 8 into engagement withthose of said sections 7. When in this position, the locking members 9,carried by the respective reinforcing corners, will extend longitudinalof the side sections and exterior thereof, with their upper edges in.alinement with said side sections, as clearly shown in Fig. 5', Havingnowassembled the several sections, to lock the same, locking flaps 5 areoutwardly and downwardly folded on scores 4', which brings their outersurfaces in engagement with those of locking members 9, as shown in Fig.6. For the purpose of securing locking flap 9 in operative position,staples 10, wire stitches, or other suitable fastening elements may beemployed.

Arranging and locking the assembled sections as outlined effects anextremely durable construction, as it affords a reinforcement to allvulnerable points. Ordinarily the side sections are subject to more orless strain, especially in the vicinity of their lateral edges,consequently, by providing the reinforcing corners, an additional doublethickness of material is provided at these points, which materiallystrengthens said side sections, and disposes the aforesaid lateral edgesthereof interior of the tray. The locking flap, extending from thelooking member, not only securely retains the latter in position, makingaccidental disengagement of the several sections llllPUSSilJlQ, but alsoprovides an additional thickness of material at and contiguous the upperedges of said side sections, which is usually exposed,

and a weak factor in box construction.

In view of the above, it will be obvious that I have designed a trayconstructed from a blank, having all parts which ordinarily would besubject to the greater strain reinforced, and one which, by virtue ofthe reinforcing corner construction, is capable of serving as acontainer of liquids, without possibility of the latter escaping.

Having now described my invention, what I claim is 1. In a receptacleformed from a one piece blank, the combination with a bottom section andupwardly foldable side and end sections, of off-setting wings carried bysaid end sections, the outer lateral edges of said wings being adaptedto register with those of said side sections, corner portions situatedintermediate the lateral edges of said wings and side sections, saidportions being formed in sections conjointly foldable exterior of theside sections, locking members carried by said corner portions andadapted to extend longitudinal of the side sections, and locking flapsformed on the upper edges of said side sections, said flaps beingdownwardly foldable into engagement with said locking members,substantially as and for the purpose set forth.

2. In a receptacle formed from a one piece blank, the combination with abottom section and side and end sections folded upwardly'therefrom; of asectional corner portion intermediate the lateral edges of said side andend sections, the sections of said corner portion being conjointlyfoldable exterior of the side sections, locking members carried by saidcorner portions and adapted to extend longitudinal of the side sections,and locking flaps formed on the upper edges of said side sections, saidflaps being downwardly foldable into engagement with said lockingmembers, substantially as and for the purpose set forth.

3. In a receptacle formed from a one piece blank, the combination with abottom section, and upwardly foldable sideand end sections; ofoffsetting wings carried by said end sections, the outer lateral edgesof Said Wings being adapted to abut those of said side sections, cornerportions situated intermediate the lateral edges of said Wings and sidesections, said portions being formed in sections conjointly foldableexterior of the side sections, and interlocking means in connection Withsaid side sections and corner portions, substantially as and for thepurpose set forth.

4. In a receptacle formed from a one piece blank, the combination With abottom section and upwardly foldable side and end sections; ofoffsetting Wings carried by said end sections, corner portions situatedinter mediate the lateral edges of said Wings and side sections, saidportions being formed in sections conjointly foldable exterior of theside sections, locking members carried by said corner portions andadapted to extend longitudinal of the side sections, and locking flapsformed on the upper edges of said side sections, said flaps beingdownwardly foldable into engagement with said locking members,substantially as and for the purpose set forth.
